It's umpteen years since I've been on a commercial flight with my tripod. Is there any problem with putting a tripod in your carryon? I want to take my trusty Bogen 3021 (no pointy feet) with me, but I hadn't planned on checking any baggage on this trip (domestic US flight -- US Scareways).

As long as your carry-on bag will take 24.1" for the length of the tripod folded down and your air carrier will allow a carry-on bag that is at least 24.1", you should be good to go. Always add on some padding to those numbers and check with your carrier.

I plan to travel this year and have decided to rent tripod legs at my destination rather than travel with it. I will carry my ball heads though and just rent the legs.
